Asymmetric Digital Subscriber Line (ADSL)

Introduction

The Cisco 1700, 2600, and 3600 series routers support the asymmetric digital subscriber line (ADSL) WAN interface card (WIC). All three platforms have essentially the same configuration. But there are differences in hardware and in the Cisco IOS® Software release that each one requires. This document refers to the Cisco 1700/2600/3600 as the Cisco ADSL WIC.

This sample configuration shows a Cisco ADSL WIC with ATM adaptation layer 5 (AAL5) multiplex (MUX) encapsulation that supports multiple permanent virtual circuits (PVCs). The Cisco ADSL WIC connects to a Cisco 6130 Digital Subscriber Line Access Multiplexer (DSLAM) and terminates at a Cisco 6400 Universal Access Concentrator-Node Route Processor (UAC-NRP). This document also includes configurations for the Cisco 6130 and Cisco 6400.

This example uses IP for both PVCs to demonstrate the map to the Cisco 6400 UAC-NRP.

Prerequisites

Requirements

Before you attempt this configuration, ensure your use of one of these software releases:

• Cisco 6400 UAC-NRP Cisco IOS Software Release 12.1(3)DC1

• Cisco 6400 UAC-Node Switch Processor (NSP) Cisco IOS Software Release 12.1(3)DB

• Cisco 6130 DSLAM-NI2 Cisco IOS Software Release 12.1(5)DA

Components Used

To support the ADSL WIC on the Cisco 2600 or 3600, this hardware is a requirement:

• 2600: Chassis WIC slots, NM-2W

• 3600: NM-1FE1R2W, NM-1FE2W, NM-2FE2W, NM-2W

  Note: For the Cisco 3600, ADSL does not have support on WIC NM-1E1R2W, NM-1E2W, or NM-2E2W.

To support the ADSL WIC, these Cisco IOS Software releases are a requirement:

• Cisco IOS Software Release 12.1(5)YB or later (Plus versions only) on the Cisco 2600 or 3600

• Cisco IOS Software Release 12.1(3)XJ or later (Plus versions or ADSL feature set only) on the Cisco 1700

  Note: The "y7" in the image name identifies the ADSL feature set, for example, c1700-sy7-mz.121-3.XJ.bin.

Note: When you download the image for the Cisco 1700, make sure that you select the image name of 1700. Do not download a 1720 or a 1750 image; the features do not support the ADSL WIC.
